Dear Dr. Hock; 
Dr. W. A. Orton, of this Bureau, has asked me 
to find out, if I can, in regard to the existence of 
a mustard which is grown in China for the root, which 
root is used as a vegetable. If you get track of any such 
variety, do not fail to get some seed of it or find out 
where we can get it. 
Enclosed you will find a note prepared by Mr. 
# 
Bussell in regard to maps of Siam which he got at my 
request from the Siamese Legation. 
With kind regards, I remain. 
Very sincerely yours. 
Agricultural Explorer in Charge.
